One third of onshore high voltage cables and three quarters of ducts installed for first two phases of Dogger Bank Wind Farm

3rd December 2021 in Construction, Press releases, Project news, Supply Chain

Three quarters of the ducts and a third of the on-shore high voltage cables that will connect the first phases of the world’s largest offshore wind farm to the UK’s National Grid have now been installed.

Jones Bros Civil Engineering UK is delivering the land-based infrastructure for the first two phases of Dogger Bank Wind Farm, which will connect to the National Grid near Beverley, East Riding. There are also a number of UK-based specialists supporting the Jones Bros team with the cable installation work.

The North Wales-headquartered company is responsible for installing 80 miles of underground cabling in underground ducts on land in East Riding of Yorkshire from the landfall site at Ulrome, to the onshore convertor station near Beverley.

With wetter weather now closing in, much of the site is entering a winter shutdown in order to preserve the quality of the soil. However, some drilling work will continue into the new year under the A1079 north of Woodmansey, and at the Creyke Beck Substation, with the tier one contractor planning to complete this by Spring 2022.

Onshore works manager for Dogger Bank Wind Farm, Oliver Flattery, said:

“Great progress has been made over the last few years to prepare the land-based infrastructure for the first two phases of the world’s largest offshore wind farm.

“We remain committed to operating safely, sustainably and respectfully as we continue our drilling work in East Riding of Yorkshire, and as duct and cable installation work picks up again in the Spring.”

James Lockwood, project manager for Jones Bros, said:

“We have made excellent progress while the weather has been with us, and as such have installed a significant amount of cable.

“The cable itself runs across two routes: a DC route which goes from the connection point with offshore cables to the converter station, and a shorter AC route, which then runs from the converter station to National Grid infrastructure.

“Additionally, we have been able to start some works restoring parts of the site, a process which includes sowing a mix of specially selected cover crops that will help maintain the nutrient levels in the soil in preparation of the final reinstatements work due to carried out next year.

“Once better weather returns in the spring, we’ll be back underway with high voltage duct and cable installation, working towards a final site handover in June 2023.”

The team has also constructed 28 of the project’s 74 joint bays, which will form part of the infrastructure for the connection between offshore power cables and the mains grid.

Dogger Bank Wind Farm, which is being built more than 130km off the Yorkshire coast in the North Sea, is currently being developed in three 1.2GW phases: Dogger Bank A, B and C.

Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). In November 2021 SSE Renewables and Equinor, 50:50 joint venture partners in Dogger Bank C, announced Eni will take a 20% stake in the final phase, with SSE Renewables and Equinor maintaining 40% stakes each. The deal is expected to complete in Q1 2022, subject to  regulatory approvals.

DOGGER BANK C REACHES FINANCIAL CLOSE

2nd December 2021 in Construction, Press releases, Project news, Uncategorised

Joint venture partners SSE Renewables and Equinor have reached financial close on Dogger Bank Wind Farm C, the third phase of what will be the world’s largest offshore wind farm when complete in March 2026.

SSE Renewables and Equinor are already constructing the first two phases of the 3.6GW Dogger Bank Wind Farm with Eni, joint venture partner on phases A and B of the world-leading offshore wind project to be installed off the north east coast of England. Now, with financial close being reached on the project’s third phase, Dogger Bank Wind Farm has passed the last important milestone ahead of its construction delivery programme.

Total investment in Dogger Bank Wind Farm will be around £9 billion, of which around £3 billion is for phase C including offshore transmission capex in the range of £900-1000m.

Dogger Bank C has a capacity of 1,200MW and will generate around 6TWh. In total, Dogger Bank will produce enough clean, renewable electricity to supply 5% of the UK’s demand, equivalent to powering six million UK homes.

Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). On 2 November 2021 SSE and Equinor announced the sell down of a combined 20% share in Dogger Bank C to Eni (10% each) for a total consideration of £140m. The transaction is expected to close in Q1 2022, subject to regulatory and lenders approvals and customary purchase price adjustments. Eni will enter the asset effective from completion of the sell down transaction. Once the transaction is complete, the new overall shareholding in Dogger Bank C will be SSE Renewables (40%), Equinor (40%) and Eni (20%). Extended partner alignment will enable further synergies across, both in the construction and operations phase of the Dogger Bank wind farm.

Dogger Bank Wind Farm is pioneering new technology and breaking world records in its delivery including green financing records. Financial close on Dogger Bank C has been reached through the financing support of a group of lenders comprising 28 banks and three export credit agencies (ECAs). Taken in aggregate with the financing last year of the A and B phases of the Dogger Bank project, reaching Financial Close on all three phases of Dogger Bank Wind Farm is the largest offshore wind project financing to date globally.

Alistair Phillips-Davies, SSE Chief Executive, said: It is a fantastic achievement to be reaching financial close on the third phase of the world’s largest offshore wind project, just weeks after COP26 concluded in Glasgow and today marks an important early milestone in the delivery of our own Net Zero Acceleration Programme. Our plans will enable delivery of over 25% of UK’s 2030 40GW offshore wind target, whilst also expanding overseas, delivering over 20% of upcoming UK electricity networks investment and deploying the critical flexibility technologies to provide security of supply.

“Construction is well underway on the first two phases of Dogger Bank with work on the third phase already progressing and we look forward to this ramping up in the New Year. As well as providing clean, green power, Dogger Bank is enabling the planned GE blade manufacturing plant in Teesside and a huge number of direct and indirect jobs.

Pål Eitrheim, Equinor EVP of New Energy Solutions, said: Reaching financial close on the third phase of Dogger Bank is a significant milestone as it demonstrates that we are on track with developing what will become the world’s largest offshore wind farm. The extensive interest from lenders underpins the attractiveness of UK offshore wind assets and the confidence in SSE and Equinor as developers. The level of interest achieved reflects the quality of the project and enables strong return on equity. As the wind farm’s future operator, we will leverage our offshore execution capability and continue to deliver value for years to come.”

Dogger Bank C is being project financed with gearing of c.70% for the generation assets. Gearing on the transmission facilities is set at 90% of the forecast OFTO sale proceeds, in line with standard market practice in the sector. Total senior debt facilities is around £2.5 billion plus ancillary facilities of around £435 million.

With the strong interest from lenders, Dogger Bank C was able to secure competitive terms, despite continued impact from the coronavirus pandemic on the macroeconomic environment. The final group of lenders includes experienced lenders, many of which are relationship lenders of both SSE and Equinor. The majority of lenders are the same as for the financing of Dogger Bank A and B, reached in November 2020.  A list of Dogger Bank C lenders, ECA and Advisors is available to download here.

SSE Renewables is leading on the development and construction of Dogger Bank Wind Farm, and Equinor will operate the wind farm on completion for its expected operational life of around 35 years.

Power Purchase Agreements signed for Dogger Bank C

24th November 2021 in Press releases, Project news

  • 15-year offtake Power Purchase Agreements (PPAs) signed for the third phase of the world’s largest offshore wind farm. 

24 November 2021: SSE Renewables and Equinor, the joint venture partners co-developing the 3.6GW Dogger Bank Wind Farm in the North Sea, have announced today that 15-year offtake Power Purchase Agreements (PPAs) have been signed for the third phase of the world’s largest offshore wind farm.

Dogger Bank Wind Farm will be constructed over 130km out to sea off the north-east coast of England, where wind speeds are higher and more consistent than near to the shore. Due to its size and scale, Dogger Bank Wind Farm is being built in three consecutive 1.2GW phases; Dogger Bank A, Dogger Bank B and Dogger Bank C. Each phase is expected to generate around 6TWh of electricity annually, totalling 18TWh annually across all three phases – that’s enough renewable electricity to supply 5% of the UK’s demand and equivalent to powering six million UK homes.

Once the three phases are complete, which is expected by March 2026, Dogger Bank will be the largest offshore wind farm in the world.

Separate PPAs for a total of 1.2GW for Dogger Bank C have been concluded with sponsor offtakers Danske Commodities (40% share) on behalf of Equinor and SSE Energy Supply Limited (20% share) on behalf of SSE Renewables, and also with external offtakers Centrica Energy Marketing and Trading (20% share) and Shell Energy Europe Limited (20% share). The agreements are subject to Financial Close on Dogger Bank C, which is expected by the end of 2021.

The deals to buy the power generated by the third phase of the wind farm follow the conclusion of a competitive bidding process.

Danske Commodities will have trading and balancing responsibility for 480MW while Centrica Energy Marketing and Trading, Shell Energy Europe, and SSE Energy Supply will have responsibility for 240MW each of installed generation capacity across Dogger Bank C.

Steve Wilson, Dogger Bank Wind Farm’s Project Director at SSE Renewables, said:

“Today we’re celebrating yet another important milestone in the delivery of the world’s largest offshore wind farm. Concluding offtake Power Purchase Agreements with some of the leading energy trading companies for Dogger Bank C means we are well on track to reach financial close for the third phase of Dogger Bank Wind Farm by the end of the year.

“I’m particularly pleased the agreements being announced today see existing project offtake partnerships being extended across all three phases of the wind farm as well as a new project offtake relationship being forged. Working together daily with our offtake partners we’ll bring new green energy from the world’s largest offshore wind farm to the National Grid so that we’re powering change for a net zero future for millions of UK customers.”

Halfdan Brustad, vice president for Dogger Bank at Equinor, said:

“Securing offtake agreements for Dogger Bank C is very exciting as it brings us one step closer to Financial Close for the third phase of the project. Following close behind Dogger Bank A and B, development of Dogger Bank C is progressing well and we hope to be able to reach Financial Close by the end of this year. With this, we will really start to see the magnitude of this world-leading offshore wind farm, and the benefits that a project of this size can bring both to the UK, and wider offshore wind industry.”

Dogger Bank Wind Farm secured 3.6GW of offshore wind contracts in the UK Government’s 2019 Contracts for Difference (CfD) auctions. The CfDs awarded provide overall price certainty to each phase of Dogger Bank Wind Farm for a period of 15 years.

The offtake PPAs being announced today for Dogger Bank C cover a matching 15-year term from the start of the CfDs awarded to each project. The commercial power agreements provide a route to sell the green energy generated by the third phase of the wind farm into the GB electricity market when it enters commercial operation.

Tor Mosegaard, VP, Head of European Power Trading, Danske Commodities, said:

“The PPA with Dogger Bank C is a great addition to our long-term portfolio and it shows our commitment to British renewables. Danske Commodities has traded power in the UK for more than ten years and we see PPAs as a crucial part of ensuring the continued development of renewables.”

Finlay McCutcheon, Managing Director of Energy Portfolio Management at SSE, said:

“We are delighted to secure this landmark power purchase agreement, which will see SSE Energy Supply offtake 20% of the renewable energy generated by Dogger Bank C when it becomes fully operational from 2026. Combined with our agreements for Dogger Bank A and B, we’re proud to be bringing a massive 720MW of green electricity from the world’s largest offshore wind farm to customers across the UK, driving the transition to a net zero future.”

Cassim Mangerah, Managing Director of Centrica Energy Marketing and Trading said:

“We are proud to take a significant proportion of the output from Dogger Bank which, once complete, will be a very important energy resource for the UK. The signing of this deal further underlines our reputation as a leading player in European energy markets and will help us to deliver on our commitment to help our customers live more sustainably and more affordably.”

David Wells, Vice President of Shell Energy Europe Limited, said:

“Offshore wind is playing an increasingly important role in supplying the UK with low-carbon electricity. This agreement expands our portfolio of clean power and increases to 720MW our combined offtake from Dogger Bank, one of the most ambitious renewable power projects in the world.”

The ground-breaking Dogger Bank Wind Farm project is breaking world records and pioneering new technology in its delivery. It will be the first project to use GE Renewable Energy’s Haliade-X 14 MW, the first offshore wind turbine in the world to operate at 14 MW, and due to its distance from shore, the first UK High Voltage Direct Current connected wind farm.

Onshore construction began in 2020 and is currently underway for Dogger Bank A and Dogger Bank B, with offshore construction on Dogger Bank A due to begin in Q2 2022. First power is expected in Summer 2023 and Summer 2024 for Dogger Bank A and B, respectively, with commercial operations to follow around 6 months later. Turbine installation for Dogger Bank C will begin in 2025.

Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). In November 2021 SSE Renewables and Equinor, 50:50 joint venture partners in Dogger Bank C, announced Eni will take a 20% stake in the final phase, with SSE Renewables and Equinor maintaining 40% stakes each, in a deal that is expected to complete in Q1 2022 (subject to Dogger Bank C Financial Close and regulatory approvals.)

SSE Renewables is leading on the development and construction of Dogger Bank Wind Farm, and Equinor will operate the wind farm on completion for its expected operational life of around 35 years.

Construction starts on operations and maintenance base for world’s biggest offshore wind farm

22nd November 2021 in Operations, Press releases, Project news, Supply Chain

Dogger Bank Wind Farm has officially broken ground for its net zero carbon Operations and Maintenance (O&M) Base at the Port of Tyne.

At 3.6GW, the wind farm will become the biggest in the world when fully operational in 2026, and be capable of providing around 5% of the UK’s electricity.

The Government has committed to decarbonize the UK’s electricity system by 2035, and anticipates that by 2030 offshore wind could generate enough electricity to power every UK home.

SSE Renewables is leading on the construction of the wind farm, and Equinor will operate the wind farm from the new base, for its operational life expected to be 35 years.

Mark Halliday, Operations Director for Dogger Bank, said:

“Dogger Bank Wind Farm will be a large contributor to the UK’s net zero ambitions, at the same time creating jobs and bringing investments to the local economy.

“This ground-breaking is a proud moment for the project and marks the start of more than 35 years’ presence by the Dogger Bank operations team here at Port of Tyne.  As well as building a state-of-the-art facility, we are looking forward to building up a fantastic team based here and working with others in the region to develop a world-leading offshore wind cluster.”

Matt Beeton, CEO Port of Tyne said:

“It is a huge win for the region that the Operations and Maintenance base for the world’s biggest offshore wind farm will be right here at the Port of Tyne. Being home to Dogger Bank firmly places the north-east at the centre of the offshore energy transition, and we are already seeing ripple effects within the local offshore wind supply chain. As our first resident of the Tyne Clean Energy Park, we are confident this base will attract other significant manufacturing and operational businesses to the Tyne.”

Dogger Bank Wind Farm will be located more than 130km offshore, and the Operations and Maintenance Base will be the onshore hub for the wind farm.

Over 200 people will be based there or offshore to operate and maintain the 277 turbines and associated infrastructure needed to generate power for millions of homes. Recruitment will ramp up in 2022, as the project looks to fill roles including wind farm technician, project planners, engineers and management.

As well as offices for those based onshore and a warehouse to store spare parts for the wind farm, the design includes development of a new quay suitable for the state-of-the-art Service Operations Vessels (SOVs) that provide accommodation, and transport for technicians to and from the wind farm. The vessels will come to the port approximately twice a month for resupply and crew change.

The 3400m2 base is expected to complete in Q4 2022, ahead of wind farm operations starting in 2023. The construction of the O&M base is being managed by Equinor, which has contracted global real estate advisor CBRE as the Principal Designer, and Bowmer + Kirkland (B+K) as the Principal Contractor for the facility.

The O&M base will be constructed and operated in line with the UK Green Building Council’s (UKGBC) Net Zero Carbon Buildings Framework to ensure transparent and robust reporting of its sustainability credentials. It will use low carbon materials and will meet the highest energy efficiency classifications. Solar PV panels will be installed for onsite renewable generation, and EV charging points will be available so staff and visitors can travel there in low emissions vehicles, further reducing the wider impact.

Construction of other parts of the wind farm has already begun, with onshore cabling works progressing well despite the global pandemic.

Dogger Bank Project Director, Steve Wilson, said: 

“Today we’re celebrating the start of work to build this innovative zero carbon base, but it’s also a great chance to take stock and celebrate what’s already been achieved since the overall construction of the wind farm commenced in early 2020.

“With around a third of the onshore high voltage cables now in place for the first two phases of the wind farm and the first onshore convertor station starting to take shape, we’re looking forward to getting started on the offshore installation work during 2022 that will be critical to this world-leading renewable energy asset becoming fully operational from 2026.”

The project is being built in three phases; Dogger Bank A, B and C. Dogger Bank A and B are a joint venture between Equinor (40%), SSE Renewables (40%), and Eni (20%). In November 2021 Equinor and SSE Renewables, 50:50 joint venture partners in Dogger Bank C, announced Eni will take a 20% stake in the final phase, with SSE Renewables and Equinor maintaining 40% stakes each. The deal is expected to complete in Q1 2022 subject to Dogger Bank C Financial Close and regulatory approvals.

 

 

Ryder Geotechnical providing local expertise to Dogger Bank

16th November 2021 in Construction, Press releases, Project news, Supply Chain

The world’s largest offshore wind farm is once again benefiting from supply chain expertise in the north-east of England as it continues site preparation work for the installation of turbines in the North Sea.

Working in collaboration with Global Maritime, Newcastle-based Ryder Geotechnical, a Tekmar Group company, delivered a site-specific assessment in preparation for the installation of 190 turbines for the first two phases of Dogger Bank Wind Farm.

The wind farm is being built in three phases; Dogger Bank A, B and C, and when complete will be able to generate around 5% of the UK’s electricity. The project will use the world’s first Ultra-Low emissions jack-up vessel to install turbines 130km out to sea, off the North East coast of England.

Turbines are installed by a jack-up vessel, a ship that extends legs down to the seabed and lifts itself up to provide a stable platform to perform installation from. Ryder’s role in this project was to assess the geological conditions above and below the seabed surface at both sites and provide geotechnical information ahead of the jack-up operations. The geotechnical information is used to advise on the seabed load bearing and other parameters needed for installation.

Steven Metcalfe, lead engineer on the project from Ryder said “We’re delighted to have this opportunity to work on the world’s largest offshore wind farm. The site was particularly complex geologically due to soft clay layers sandwiched between firmer sand layers, but working closely with Global Maritime we were able to fully assess these holistically, and develop solutions for the safest operations.”

Dogger Bank A and B is a joint venture between SSE Renewables (40%), Equinor (40%) and Eni (20%). In November 2021 SSE Renewables and Equinor, 50:50 joint venture partners in Dogger Bank C, announced Eni will take a 20% stake in the final phase, with SSE Renewables and Equinor maintaining 40% stakes each, in a deal that is expected to complete in Q1 2022 (subject to Dogger Bank C Financial Close and regulatory approvals).

SSE Renewables is leading on the construction of the wind farm and Equinor will operate the wind farm for its expected lifetime of 35 years.

Halfdan Brustad, Vice President for Dogger Bank at Equinor said: “This site-specific assessment carried out by Ryder Geotechnical is essential for us to confirm the turbine fixing requirements ahead of construction and to understand any geotechnical risk to jack-up operations, ensuring safe installation offshore. It’s another great example of UK expertise helping us to deliver the wind farm safely and efficiently as we prepare for offshore installation to commence in 2022.”
